ABSTRACT

The effect of organic salt tetramethylammonium bicarbonate (TMAC) at salt mole fractions from 0 to 0.159 on the vapor liquid equilibrium (VLE) of the binary methanol water system has been experimentally investigated at 101.32 kPa using a modified Rose equilibrium still. The experimental data were correlated by Ohe's preferential solvation model and the Tan Wilson model, and the average deviations of the vapor-phase mole fraction of this salt-containing methanol water system are 0.011 and 0.017, respectively. The average deviations of temperature are 1.24 K for Tan's model.
